We have covered this in the past. This was the FIRST announcement for touring the facility. The second announcement for an additional tour, (which occurred before this one) allowed phones, cameras, etc. There is no reason why they would not allow electronics on this tour.
Dude, They said the same thing last time, then changed the request to allow phones...etc...., lolzzzzzz, cat is out of the bag, expansion is moving full steam! Denial is Futile! SIGO
